The newspaper, which essentially acts as a mouthpiece for Kim’s government, said: “The NPR [Nuclear Posture Review] is nothing but an open declaration of war by the rogue state which means to dare make a preemptive nuclear strike on the DPRK in order to bring the Korean peninsula and the world into a nuclear holocaust.

“The NPR invented by the Trump group is a product of the black-hearted intention to realise the ambition for aggression by starting a nuclear war on the Korean Peninsula at any cost.”

The piece said Mr Trump’s threats would only result in American pain and suffering – and warned of a “decisive military strike” on the US mainland.
